‘Torrents of Terror’: the August 1998 Storm and the Magnitude,Frequency and Impact of Major Floods in the Illawarra Region of New South Wales

The Illawarra Region some 80 kilometres south of Sydney is characterised by a prominent coastal escarpment that rises to 700 m within 12 km of the coast and forms a locus for frequent, high intensity rainfall events. One of the most recent recorded events occurred on 17 August 1998 with rainfall intensities at several pluviometers exceeding 120 mm hr^‐1 over a duration of one hour, with up to 249 mm falling in 3.5 hours during the main storm burst. Detailed pluviometer data indicate that the storm was non‐stationary and moved down catchment producing a widespread zone of 120 mm hr^‐1 intensity rainfall over a 30 minute duration across mid‐lower catchment areas after similar intensity but longer duration rainfall in catchment headwaters. Slope‐area reconstructions of peak discharge indicate that small catchments on the escarpment within the zone of maximum intensity experienced close to 100% rainfall‐runoff relationships, with peak discharges correlated to short duration (<1 hr) peak rainfall intensities. Widespread erosion occurred particularly where urban development had encroached on natural water courses. Debris/hyperconcentrated flows originating from both anthropogenic and natural sediment sources caused damage to urban areas. This paper provides an overview of the spatial and temporal characteristics of the 17 August 1998 storm, the hydrologic and geomorphic response of the streams, and the nature of damage to urban areas. It reassesses the frequency of recent high‐magnitude rainfall/flood events in the region, discussing the relationships between rainfall intensities, estimates of flood magnitudes and stormwater channel capacities.     

Industrial spaces for grassroots creative production: spatial,social and planning facets

Former industrial premises provide material and symbolic resources for grassroots creative production, but planning is complex as these sites are transitory and excessive intervention may stifle creativity. This paper analyses the transformations of La Ribera (Bilbao), a mixed-use peninsula waiting to be redeveloped, where, in the meantime, creative-based grassroots projects have settled. Drawing upon relevant planning documents, documentary material and interviews with key actors, the paper explores (i) the spatial and built form advantages of these spaces, (ii) their impact on neighbourhood life and (iii) the contradictions faced in the planning process. The analysis suggests that spatiality plays a critical role, but it is threatened by market pressures, local governments’ interest to encourage the city's reputation and neighbours’ mistrust for the changes they may trigger. As a result, we contend that art spaces’ institutionalization in the neighbourhood is decisive for their sustainability, but the conflicts that arise for the symbolic appropriation of space should be considered. Regarding policy, governance approaches that preserve users’ autonomy and spaces’ built form and atmospheric qualities are rather suitable responses if they are part of a comprehensive agenda that includes local socio-economic conditions and neighbours’ aspirations.     

Production risk,inter-annual food storage by households and population-level consequences in seasonal prehistoric agrarian societies

Abstract

Using complementary behavioural and population ecological models, we explore the role of production risk, normal surplus and inter-annual food storage in the adaptations of societies dependent on seasonal agriculture. We find that (a) household-level, risk-sensitive adaption to unpredictable environmental variation in annual agricultural yields is a sufficient explanation for the origins of normal agrarian surplus and, consequently, of household-level incentives for inter-annual food storage; and, (b) at the population level, density-dependent Malthusian processes tightly constrain the circumstances under which this same mechanism can be effective in smoothing inter-annual fluctuations in household food availability. Greater environmental variation and higher levels of fixed set-asides such as seed requirements or transfer obligations to political authorities lead to more severe, periodic famines; however, outside of famine events, these same factors improve average population welfare by suppressing population density to levels at which Malthusian constraints have lessened impact. The combination of behavioural and population ecological modelling methods has broad and complementary potential for illustrating the dynamic properties of complex, coupled human–natural systems.

Momentarily immobile: Backpacking,farm work,and hostels in Bundaberg,Australia

The Working Holiday Maker visa encourages young people from 44 nations to live and work for up to three years in Australia, contributing immensely to the temporary migrant workforce in regional areas. However, the conditions they experience while completing 88 days of mandatory ‘farm work’ to apply for visa extensions often place them in vulnerable situations and states of immobility that are counter to the perception of backpackers as mobile. Types of accommodation specifically for temporary migrant farm workers are known as working hostels and in some cases the ways in which they are administered have perpetuated the precarious and immobile situations in which backpackers find themselves. This article explores the lived experiences of backpackers who have undertaken farm work in the Bundaberg region, a new ‘hot spot’ for seasonal migrant labour. Drawing on ethnographic observations and interviews with 35 working holiday makers, the article advances the suggestion that recent shifts in hostelling accommodation practices and increased competition for agricultural jobs in the region place individuals in increasingly precarious states of immobility.     

The Marriage Well at Teltown: holy well ritual at royal cult sites and the rite of temporary marriage

This article discusses Lag an Aonaigh, the ‘Marriage Well’ of Teltown, and the unusual temporary marriage ritual that once took place there during the annual Lughnasa festival. The relationship of Lag an Aonaigh to the modern and ancient fairs (aonach and óenach), and to the broader cult of holy wells is considered, which it is suggested largely represents the local adoption of the Mediterranean healing-spring cult. The article investigates the possibility that this marriage rite was informed by lore of a divine wedding at Teltown, and by the inaugurations carried out at many royal centres that entailed the matrimonial symbolism of the king marrying the Goddess of the land. The relationship of this site to the broader landscape of Teltown, especially to the nearby Knockans linear earthwork is explored. This relationship is then used to analyse the landscapes of the other main ‘royal’ sites, where linear earthworks similar to the Knockans that terminate near springs or ponds are also found. It is considered that all of these earthworks may have been used in ritual processions involving the springs, or even as devices to segregate young men and women at these assemblies, and lead them to the spring to start their own ‘Teltown weddings’.     

Economic fears of mass migration from southern Italy in early twentieth century America

ABSTRACT

Economic fears in the early twentieth century America about Italian immigration united trade unions and white collar workers and were motivated by reasons that ranged from the belief that migrants were disrupting the labour market and were temporary opportunist earners, unwilling to integrate and living in isolated communities, to the idea that southern Italians did not offer sufficient human capital: they were mainly illiterate, and had high dropout rates in schools, and were widely believed to have children with mental disabilities. These American fears were wildly overstated, however. First, Southern Italian migrants had to undergo a two-stage positive selection for literacy, while, secondly only 28.4 per cent of the massive incoming flow of Italians decided to stay; most Italian immigrants chose to return to their country of origin and the minority who remained did not delay long to join in the American melting pot.     

Protective Structures for the Preservation of Medieval Buildings and their Remains: Case Studies from Monastery Hilandar and Mount Athos

The objective of this study is to establish a methodology for temporary protective structures, that is, the guidelines for planning, design, and implementation of future protective structures. The basic method of this paper was the observation and analyses of temporary protective structures as well as the evaluation of the results achieved in implementation of these rules in completed structures, within the Hilandar Monastery complex on Mount Athos, in Greece. Mount Athos was inscribed on the UNESCO World Heritage List for its cultural and natural values. The Holy Mount Athos is a unique monastic complex in the world and only males are allowed past the entrance. Having performed the evaluation of certain types of temporary protective structures, the given results were offered as recommendation for their design and implementation. The most significant accomplishment of this paper is verification of the designed, calculated, and completed protective structures through practical application within the Hilandar Monastery complex, in accordance with all the factors of site management.     

Towards an archaeology and geography of Second World War German munitions storage sites in north-west Europe

This paper reviews the signature characteristics of extant Second World War German army munitions storage landscapes in forested areas of north-west Europe with particular reference to sites in north-west France and the Netherlands. Archaeological survey, aerial photographs and documentary archives show the geography of munitions sites exhibit a regulated pattern of bunker disposition and spacing that is adapted to local road configurations and terrain. Non-hardened bunkers form the predominant feature in munitions depots and conform to a five-/six-fold typology defined by non-invasive survey and excavated examples from the Netherlands. The typology reflects an evolution of storage protocols towards all-round protection from the effects of weather and blast, but also reveals variation in size, structural characteristics and function that poses questions for further study. It is anticipated that these results will be of diagnostic value in future Second World War conflict archaeological survey of German military support structures in formerly occupied territories.
